Use of off-label drugs in the neonatal intensive care unit in India

Background: Off-label use of drugs is widespread in pediatrics and almost all neonates hospitalized in NICU are affected by the use of off-label drugs regardless of gestational age and birth weight. This is because of the lack of regulation for medications in the neonatal population and the delays in updating drug instructions. This is mainly due to the ethical difficulty in the research and difficulties in conducting clinical trials in this vulnerable population. Hence, the study was planned to assess the extent of the use of off-label drugs in the NICU. Methods: An observational study was carried out in the NICU of a tertiary care center from May 2021 to Oct 2022 and case records of neonates admitted to the NICU were evaluated. Results: Among 1745 drug prescriptions in 360 neonates, 1208 (69.22%) were off-label. Anti-infectives were the most commonly used off-label class of drug, Piperacillin+tazobactam was the most commonly used off-label drug and most common reason for off-label prescriptions was indication and administration. It was found that 79.44% of neonates received at least one off-label drug. Conclusions: Off-label use of drugs, specifically anti-infective drugs, is common in NICUs of India as in other countries. So, more research should be done to generate evidence-based guidelines for the rational use of drugs in neonates

Intermediate follow-up following intravascular stenting for treatment of coarctation of the aorta

Background : We report a multiinstitutional study on intermediate-term outcome of intravascular stenting for treatment of coarctation of the aorta using integrated arch imaging (IAI) techniques. Methods and Results : Medical records of 578 patients from 17 institutions were reviewed. A total of 588 procedures were performed between May 1989 and Aug 2005. About 27% (160/588) procedures were followed up by further IAI of their aorta (MRI/CT/repeat cardiac catheterization) after initial stent procedures. Abnormal imaging studies included: the presence of dissection or aneurysm formation, stent fracture, or the presence of reobstruction within the stent (instent restenosis or significant intimal build-up within the stent). Forty-one abnormal imaging studies were reported in the intermediate follow-up at median 12 months (0.5–92 months). Smaller postintervention of the aorta (CoA) diameter and an increased persistent systolic pressure gradient were associated with encountering abnormal follow-up imaging studies. Aortic wall abnormalities included dissections ( n = 5) and aneurysm ( n = 13). The risk of encountering aortic wall abnormalities increased with larger percent increase in CoA diameter poststent implant, increasing balloon/coarc ratio, and performing prestent angioplasty. Stent restenosis was observed in 5/6 parts encountering stent fracture and neointimal buildup ( n = 16). Small CoA diameter poststent implant and increased poststent residual pressure gradient increased the likelihood of encountering instent restenosis at intermediate follow-up. Conclusions : Abnormalities were observed at intermediate follow-up following IS placement for treatment of native and recurrent coarctation of the aorta. Not exceeding a balloon:coarctation ratio of 3.5 and avoidance of prestent angioplasty decreased the likelihood of encountering an abnormal follow-up imaging study in patients undergoing intravascular stent placement for the treatment of coarctation of the aorta. We recommend IAI for all patients undergoing IS placement for treatment of CoA. © 2007 Wiley-Liss, Inc.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/57392/1/21191_ftp.pd

Percutaneous device closure of Gerbode‐type ventricular septal defects

Key Points The Gerbode type of ventricular septal defect is rare and can be congenital or acquired. The defect can be closed retrograde or through the transvenous approach. Short‐term follow‐up suggests that transcatheter closure of the Gerbode type defect is feasible, safe, and effective and should be considered an alternative to surgical repair
